Hmm.. I did French for 6 years, and I don't think another 2 years at GCSE would have actually given me any better of a grasp of the language, since I can barely remember a word of it now. My school was really lax on languages though, they weren't compulsory at GCSE (which I think would have to change if foreign languages were to become a demand - university entry requirements did not cross my mind at all when choosing my GCSE's, so it would leave someone in such position at a disadvantage to then be told "lolsorry, should have thought about that 3 years ago" ). Actually, my school was pretty lax on everything, but there you go.
Besides, I find learning languages to be a massive pain-in-the-arse chore anyway, I took no enjoyment in it whatsoever. And it's not like a GCSE level language leaves you with any degree of fluency anyway - just "I live <here>, I like ice cream, I would like to buy an ice cream".. yeah.
